Be it known at l, LEE WARREN BAR- nnn, a citizen ot the United IStates, residing at Chieagmin the countyof Cook and State of Illinois, have invented eertain lnew and usefulA Improvements in Center-Bearings for Railway-Cars; and l de hereby declare the pllowing to be ay full, olear,f and exact c lesoript'ion` of fthe invention, suchv as will enable others skilled inthe `art Tto which it ap ertains tomi-xke and use the saine.,

y Yinyention has for its object to provide ,an improved center bearing for railway carsg, 'and to such ends, generally stated, the invention feonsists of the novel, devices :indcombinaionsof deviees hereinafter described and `finedinthe claims..

n the acloompanyinmldrawings `whieh illustrate the invention,` ,like ,eha'racters indicate likeparts throughoiitthe several views.

Referring to thedrawingsz-Figure l ,is a view partly n vertical section land partly in elevation, and with some parte broken away, s howingilthe improvedl center'bearing; Fig". l2 is, a bottom plan yiew ofthe hub portion of the upper bearing plate member, some parts being broken away; Fig. 3 is aperspective view showingaportion of a retaining ring used ont e, huby of l the upperbearing'member; and ig. Llois a side elevation .Showing e used in connection with member.

The lowerbearing member l has an uptiirned sleeve-likel hub 2,; and the upper bearing memberiisxprovded with e .Clephnin sleeve-like hub i that surrounds the said h) 2.1The bearingmembers -1 and 3 are provided with opposing conicalsurfaces on 1which areplacedopposing outwardly flaring annular-Wearing Plates 5. and@ respectively. @utwardlo its l,wearingplate G the u per bearing member 3. is jroyided with a epending thrust ilange 7 f, aolially disposed. C'Qnical being rollers 8 are interposed between the Wearing plates 5 and, (i, and their outer ends bearQagainsftHa thrust ring 9 that is seated against the thrust flange 7 of the upper bearing member. The thrustming i9nis made cireumferentially expansible and contractible by a transverse slit 10, and its periphery is slightly rounded in cross section and made to fit a correspondingly termed seat in the thrust flange 7, so that it will be held in position in the upper bearing Sipeeiiication of Letters Fate'nt.

lepeeto the Said, thrs't hnge, 'by 'its oiwii mitre-rd .pnaetensih- ,i lli retai'ing ring 1l s secured on the del'JeiidingfQnd of the liub'of the upper bearing member and, underlaps the inner edgeof the lower wearing'plate 5. Adsofit willbe noted that the lower wearin platee ufnderla'ps thel thrust ring 9. ith this arrangement, therefore, the wearing plates gind are interloclied to Athe 11PP61`1-bearing meinber 'andthe rollers 8 and thrust ring 5?l are` `gage'd betwee'n the said wearing plates, so that all of the said parts 5, 6, 8 and 9 are interloeked to the Asaid pper bearing member. Of co rse this arrangement might be reversed and a l rf thesaid niembersinter'- locked totheflower bearingfmeinber.

,The arrangement illustrated 'in the drawings andl described, is preferredf Ifor several goed reasons, among whic maybe inentionedthe `facts Itlia'tftlie illustrated constlruotrn provides 'agarran ement in. which dirt and duit 'jillvvxrlzl ltheir ,way out from between the ivearingiplates,andrain, snow andldirt doe'snot find apocket in1 which to accumulate on the lower wearing plate.

Thepetailiing ring 1 1, ley be. loeked t0 the hub ,4e fn various different lways, but preferably, as is shown, by 1an, entr'einely simple, eiiicient and novel means best shown inlfig-s, Zand 3, and wliiohldescribed, isL as follows; he said hub ,has a ije uced lower end lprovided with several, preferably twoH d iametrioally opposite, outwardly projectinglooklugs 12, and theretaining ring ll isyprovided with a `lug A( learin'gnotch 13 formed b yjtemporarilybending. a lip, le outward, as shown in 14h-g3, en this ring ,linie placed on the reducedend `of the hub @above one of the look; lugs 1 2, and with its` notch 13 alned with the other lug 12, the said ring may be easily moved into a horizontal planeabove bot of the lugs 12. AS best ,shone .1iFig .21. the .lip 1.47, beine turned bark .into therplane ofthe retainin ring; 1l., the, said. ring;i -becomes interloeke toitliesad hub et, When it ledesire'd to movethe retaining ring, the 'lpleixnust be bent back into the position shown in Fig. 3, so-as to open up the lugl clearingnoteh 13, and vthis being done, the said retaining ring may be removed by reversing the process of its application.

The individual or intermediately Jformed wearing plates 5 and 6 and `thrust ring 9 make practical the use of cast steel bearing members having littlev or no finish, inas- -inuch as the load supporting surfaces and outer ends of the rollers have contact only with the said members 5, 6 and 9, and these members being made from" machine or tool steel, will be given the desired finish in the natural process of making the same from commercial sheets or other stock. Preferably, small and long bearing rollers are employed because these afford a greater number 'of bearing points and less taper and resulting out-thrust on the rollers, and, furthermore, give a reater degree of rotation to the rollers, which results in distributing the wear better on the rollers and reduces the tendency to flatten the same. Also, 'rollers of small diameter reduce the total height between the top and bottom ofthe bearing plates, and this is important in many instances where space is limited. Furthermore, the arrangement described permits of ready and easyreplacing or renewal of worn out bearing plates.

What I claim is:

1. In acenter bearing, the combination with upper and lower bearing members and individually formed annular wearing plates applied thereto, of radially disposed rollers v interposed between said wearing plates, said 'bearing plates having hubs telescoped, one

into the other a retaining device applied to theouter of said hubs and immediately underlapping the inner ortion of the adjacent wearing plate, the caring plate having the inner of said hubs being provided with a surface engaging the adjacent wearing plate, but terminated short of the inner edge thereof to afford clearance for said retaining dev-ice.

In 'a center bearing, the combination with upper and lower bearing members, and individually formed wearing4 plates applied thereto, of radially disposed rollers inter-' posed between said wearing plates, means interlocking b oth of said wea-rin plates to one of said bearing members, wit freedom forl rotary movements of said wearing plates with their respective bearin members and in respect to eachother, an a thrust ring directly interposed between the outer portions of said wearingplates and engageable with the outer ends of'said rollers.

3. rI`he combination with upper and lower ibearing members, the former having a depending sleeve-like hub and a depending thrust flange, and the latter having an upwardly extended sleeve-like hub telescoped into the hub of said upper member, of -individually formed annular wearing plates loosely applied to said bearing members, radially disposed conical `rollers interposed between said wearing plates, a thrust ring seated against the thrust llange of said upper bearing member and engaging the outer ends of said rollers, and a retaining iiiig interlocked to the hub of said upper bearing member and immediately underlapping the inner edge of the lower wearing plate, and thereby interlocking the said wearing plates and rollers to the upper bearing meniber.

4. The combination with upper and lower bearing members, the former having a dependinff sleeve-like hub and a depending thrust lange, and the latter having an upwardly extended sleeve-like hub tclescoped into the hub of said upper member, of individually formed annular wearing plates loosely a )plied to said bearing members, radially disposed conical rollers interposed between said wearing plates, a retaining ring interloclred to the hub of said upper bearinf member and immediately underlapping the inner edge of the lower wearing plate, and thereby interlocking the said wearing plates and rollers to the upper bearing member, and an expansiblc thrust ring spring seated against the thrust iiaiige of said upper bearing member and engaging the outer ends of said rollers.

5. The combination with upper and lower bearing members, the former having a depending sleeve-like hub and a depending thrust Harige, and the latter having an upwardly extended sleeve-like hub tclescoped into the hub of said upper member, of individually formed annular wearing plates loosely applied to said bearing members, radially disposed conical rollers interposed between said wearing plates, a. retaining ring intel-locked to the huh oi said upper bearing member and immediately underlapping the inner edge of the lower wearing plate, and thereby interlocking the said wearing plates and rollers to the upper bearing member, an expansible thrust ring spring seated against the thrust liange of said upper bearing member and engaging the outer ends of said rollers, the said thrust ring being caged between the outer portions of said wearing plates.

In testimony whereof I aiiix my signature in presence of two witnesses.
